ASP.NET Core How to bind data from body

I am really disappointed about all new staff of ASP.NET Core, the reason I cant bind data from request body to my Model (the most ordinary thing).  I have checked all my configuration, I have updated all my dependencies and run-time. Unfortunately still stacked with model binding.

This is my api method

[HttpPost("attach")]
[AllowAnonymous]
public async Task<IActionResult> AttachToBuilding([FromBody]AttachmentDto dto)

After sending request, dto always null

This is my model

public class AttachmentDto
{
    public string Identity { get; set; }
    public Guid BuildingId { get; set; }
    [Required]
    public string FirstName { get; set; }
    [Required]
    public string LastName { get; set; }
    public string MiddleName { get; set; }
    public string Phone { get; set; }
    [Required]
    public string UniqueDeviceId { get; set; }
    [Required]
    public int ApartmentNumber { get; set; }
    [Required]
    public int AgreementNumber { get; set; }
    [Required]
    public int FloorNumber { get; set; }
}

My Startup.cs ConfigurationServices method

 public void ConfigureServices(IServiceCollection services)
 {
        services.AddOptions();

        services.AddCors(options =>
        {
            options.AddPolicy("AllowAnyOrigin",
                    builder =>
                    {
                        builder.AllowAnyOrigin();
                        builder.AllowAnyMethod();
                        builder.AllowAnyHeader();
                    });
        });

        services.AddDbContext<KskEfContext>(options => options.UseSqlServer(Configuration.GetConnectionString(ConnectionName)));

        services.AddSingleton<IConfiguration>(Configuration);

        AddDependencies(services);

        services.AddMvcCore()
            .AddFormatterMappings()
            //for aspe.net core  need to add explicitly the Api Explorer service (swagger)
            .AddApiExplorer()
            .AddDataAnnotations()
        .AddJsonFormatters(options => options.ContractResolver = new CamelCasePropertyNamesContractResolver());


        services.AddAutoMapper();

        //Register the Swagger generator, defining one or more Swagger documents
        services.AddSwaggerGen(c =>
        {
            c.SwaggerDoc("v1", new Info { Title = "KSK api", Version = "v1" });
            c.IncludeXmlComments(GetXmlCommentsPath());
        });
    }

I find my configuration correct and I designed my api method like in previeos ASP.NET WebApi nothing extraordinary. It might be problem with framework version.

My dependencies from project.json (after I updated my dependencies)
